We need to be aware of “water footprints”. That is, the amount of fresh water utilized in the production or supply of goods we consume. As it turns out it takes significantly more water to yield foods that come from animals than foods that come from plants.

Food not only has a water footprint but also a carbon footprint, known as CO2e, which stands for carbon dioxide equivalent. Since carbon measurements are a bit more difficult to comprehend, it is common to equate CO2e to the distance which a car drives in miles or kilometers.

When calculating carbon emissions, some factors may include…

Is watermelon sustainable?

Yes, watermelon production is sustainable.

Is watermelon sustainable?

A 2018 Oxford University study is the most comprehensive analysis to date of the damage farming does to the planet. They found ‘avoiding meat and dairy is the single biggest way to reduce your impact on Earth’ as animal farming provides just 18% of calories but takes up 83% of our farmland.

Consuming animal products and byproducts is not environmentally friendly and is one of the worst things for the Earth. Not only is meat production wasteful, it causes enormous amounts of pollution. The industry is one of the biggest causes of climate change.

Is watermelon vegan?

Is watermelon vegan?

Yes, watermelon is vegan. Watermelon is a fruit and not an animal product or byproduct, therefore making it a vegan food. 

Animals of factory farming are suffering. They live in horrific conditions that often include confinement, physical abuse and unnatural environments. So much so that they need to receive antibiotics to keep from getting ill or spreading disease. Growth hormones allow all kinds of animals to become fatter faster and live short lives.

Additionally, the meat, poultry and dairy industries do everything they can to distance us from knowing how our food comes to be in order to keep us in the dark about what we support each time we buy animal derived products and byproducts.

Does watermelon have human rights issues?

benefits of buying fair trade, labor rights, human rights and workers rights issues

The labor involved behind each and every product cannot go unrecognized. 

In fact, known problems include workplace health and safety, child labor, gender inequality, inadequate pay, wage theft and exploitation. Additionally, workers can experience harassment, humiliation and violence and unfair employers often fail to provide laborers with access to shade, drinking water, restrooms and breaks.

In fact, fair trade organizations fight to ensure better social, environmental and economic standards. Therefore, we can improve people’s lives with foods we eat every day simply by buying products that are certified fair trade.
